Add ActiveRecord::attribute_names to retrieve a list of attribute names. This method will also return an empty array on an abstract class or a model that the table doesn't exists.

Revert "Merge pull request #423 from richardiux/master"

This reverts commit b8f08c4e, reversing
changes made to fd9df1b1.

Adding base method symbolized_sti_name to activerecord base to be used on identity map. Identity map now considers the inheritance when creating the caching keys

deprecated the use of the guard_protected_attributes argument with attributes= in AR in favor of assign_attributes(attrs, :without_protection => true)

Added assign_attributes to Active Record which accepts a mass-assignment security scope using the :as option, while also allowing mass-assignment security to be bypassed using :with_protected

Bring back support for passing a callable object to the default_scope macro. You can also just use a block.

Un-deprecate using 'default_scope' as a macro, but if you are calling the macro multiple times that will give deprecation warnings, and in 3.2 we will simply overwrite the default scope when you call the macro multiple times.

Evaluate default scopes at the last possible moment in order to avoid problems with default scopes getting included into other scopes and then being unable to remove the default part via unscoped.

Deprecated support for passing hashes and relations to default_scope, in favour of defining a 'default_scope' class method in the model. See the CHANGELOG for more details.

Add interpolation of association conditions back in, in the form of proc { ... } rather than instance_eval-ing strings

previously serialized_attributes were kept as class attribute of ActiveRecord::Base - if some attribute was defined as serialized in one subclass then it was serialized in all other subclasses as well (if it had the same name)

Revert "ARel only requires the connection from the AR class. Simply return the AR class rather than jump through hoops and store ivars"

This reverts commit d65e3b48.

ARel only requires the connection from the AR class. Simply return the AR class rather than jump through hoops and store ivars

Make serialized columns with explicit object_type return a new instance of the object instead of nil
